Abstract
The utility model relates to an earth conductor device for high -voltage insulation test of ware street lamp power is hit in built -in lightning protection, the street lamp power has confined metal casing, is equipped with the hole that supplies the wire to pass before the shell on the terminal surface, the wire anti circuit board external connection welding point short circuit that be struck by lightning absorber inside with the street lamp power, the wire passes the preceding terminal surface of shell from inside to outside to be connected through terminal surface detachable before locking device and the shell, when carrying out lightning surge and EMC when test, pass through locking device and shell with the wire before the terminal surface is connected, make to resist the absorber ground connection of being struck by lightning, when the experiment of the 2U+1000V's that carries out safe pattern dielectric strength, will wire and the preceding terminal surface separation of shell. The utility model discloses only need provide a style during street lamp power censorship test, censorship style commonality improves greatly, efficiency of software testing improves to some extent, the wire passes through PCB board welding point with anti thunderbolt absorber and realizes good short circuit, especially, it is troublesome to have saved a lot of unnecessary when customs's censorship inspection.
Description
Technical field
The utility model relates to a kind of voltage-withstand test earth lead device of built-in anti-lightning strike device road lamp power supply, belongs to road lamp power supply technical field.
Background technology
Road lamp power supply is owing to being positioned over open air, therefore anti-lightning performance is an important performance indexes, and the general all built-in anti-lightning absorber of existing road lamp power supply, therefore when thunder and lightning hits road lamp power supply, instant high-voltage can be sponged by anti-lightning absorber, guarantees the safety of LED street lamp.
The security performance of road lamp power supply, except anti-lightning test, also has the dielectric strength experiment of the 2U+1000V of safe pattern.The road lamp power supply of existing built-in anti-lightning strike device, anti-lightning strike device earth point by the copper nut in shell directly and shell assembly connection carry out ground connection.
When carrying out dielectric strength actual measurement examination, because the test duration lasts 1 minute, and anti-lightning absorber cannot bear high voltage so for a long time, cannot pass through to making this test.
Therefore, existing solution is: when doing CCC certification sample censorship test, one is provided to be with built-in anti-lightning absorber and a road lamp power supply not with built-in anti-lightning absorber respectively, when carrying out anti-lightning test and other tests, using the road lamp power supply of band anti-lightning absorber, when carrying out dielectric strength experiment, adopting the road lamp power supply not with anti-lightning absorber, censorship is caused to test needs two styles, very inconvenient.
Utility model content
The purpose of this utility model is: the voltage-withstand test earth lead device providing a kind of built-in anti-lightning strike device road lamp power supply, be integrated on road lamp power supply, same road lamp power supply can be used, carry out anti-lightning strike test, dielectric strength test and other a series of test, improve the versatility of test model.
The utility model takes following technical scheme:
A kind of voltage-withstand test earth lead device of built-in anti-lightning strike device road lamp power supply, described road lamp power supply has closed metal shell, case nose face is provided with the hole passed for wire, the circuit board external connection pad short circuit of the anti-lightning absorber of described wire and road lamp power supply inside; Described wire from inside to outside through case nose face, and is connected with case nose face is dismountable by locking device; When carrying out lightning surge and EMC test, described wire being connected with case nose face by locking device, making anti-lightning absorber ground connection; When carrying out the dielectric strength experiment of 2U+1000V of safe pattern, described wire is separated with case nose face.
Further, the front end face of described shell is detachable end face.
Further, described locking device is bolt nut structure, and the front end of described wire connects leads
Electricity sheet, for being compressed the front end face being fitted in described shell by nut.
Further, the rectangular body structure of described road lamp power supply.
Further, described circuit board external connection pad is tin welding spot.
The beneficial effects of the utility model are:
1) style need only be provided during road lamp power supply censorship test.
2) censorship style versatility improves greatly.
3) testing efficiency increases.
4) pcb board arranges pad, be connected with wire by pad soldering, thus realize the good short circuit of wire and anti-lightning absorber.
5) locking device locking and fractionation regulate very convenient, improve the convenience of tester.
6) design concept is ingenious, easy to make.
7) drop into little, obviously do not increase cost.
8) especially much unnecessary trouble is eliminated when customs's censorship inspection.
